## Homework Statement

A person's mass is 28 kg. They climb the 4.8m ladder of a slide and reach a velocity of 3.2 m/s at the bottom of the slide. How much work was done by friction on the person?

## Homework Equations

KE=1/2mv^2

PE=mgh

W=Fd

i think these are all the equations that apply

## The Attempt at a Solution

i think you could find the potential energy=28(9.8)(4.8), which equals the kinetic energy,

then i dont know what to do but i know what i did is wrong

thank you for any help
